Can you give me some details about files?

Thank you for your great code. I'm a student and a beginner of data analysis.
I want to executive your code but I have some questions. It may be a silly question, but can you give me some details about files?

---

python pretrain.py
--train_cfg config/pretrain.json
--model_cfg config/bert_base.json
--data_file $DATA_FILE
--vocab $BERT_PRETRAIN/vocab.txt
--save_dir $SAVE_DIR
--max_len 512
--max_pred 20
--mask_prob 0.15

1. config/pretrain.json
2. config/bert_base.json
3. $DATA_FILE
4. $BERT_PRETRAIN/vocab.txt

We need a $DATA_FILE as a train set, but what is vocab.txt? I can get the vocab.txt file from google's github. Just use it? or Can I customize it?(Because I want to make a bert which has lower parameters than BERT-BASE.)
Also, the ouput file model_steps_xxxx.pt is compatible with BERT in google's github?

Sorry I am not an expert, so maybe my questions are so silly. Thank you.

Sorry for the late response,

1. You can use vocab.txt from Google BERT's repo. It's risky to modify vocab.txt because it was learned from a corpus.
2. the output file is not compatible with google's code.
